The M22x60mm Track Fasteners are engineered to provide secure and durable fastening for excavator and bulldozer undercarriage assemblies. Manufactured from premium alloy steel and processed through precision hot forging, thread rolling, and advanced heat treatment, these track bolts and nuts deliver outstanding clamping force, excellent resistance to vibration, and long-term operational reliability.
Designed for demanding applications such as construction, mining, quarrying, and earthmoving, these heavy-duty fasteners maintain stable connections between track shoes, track links, and crawler chains, helping improve equipment performance while reducing maintenance frequency and unexpected downtime.
Feature | Benefit |
|---|---|
| Strong Clamping Force | Maintains secure track shoe connections |
| Anti-Loosening Design | Minimizes maintenance caused by vibration |
| Heat-Treated Alloy Steel | Improves hardness and structural durability |
| Precision Rolled Threads | Ensures reliable installation and torque retention |
| High Tensile Strength | Handles demanding operating loads |
| Superior Wear Resistance | Extends service life in abrasive environments |
| Corrosion-Resistant Finish | Protects against rust and harsh weather |
| OEM Manufacturing Standards | Ensures accurate fit and consistent quality |
The precision-engineered bolt and nut combination provides consistent clamping force that keeps track shoes securely fastened to the undercarriage, even during continuous heavy-duty operation.
Designed to withstand repeated vibration, shock loads, and constant track movement, the M22x60mm track fasteners help reduce bolt loosening and improve overall undercarriage reliability.
Premium alloy steel combined with advanced quenching and tempering technology provides excellent tensile strength, hardness, and impact resistance for demanding working conditions.
Rolled metric threads offer smoother engagement, higher thread strength, and improved torque retention compared with conventional cut threads, ensuring secure and consistent fastening.
The combination of wear-resistant materials, precision manufacturing, and corrosion-resistant surface treatment helps extend product lifespan while lowering maintenance costs.
They are designed for excavator and bulldozer undercarriage systems requiring M22 × 60 mm track bolts and matching nuts. Please confirm compatibility using your equipment model or OEM part number.
The bolts and nuts are manufactured from premium alloy steel and undergo precision heat treatment to achieve high tensile strength, wear resistance, and long service life.
Crawler undercarriage systems experience continuous vibration, shock, and heavy loads. Reliable anti-loosening performance helps maintain secure fastening, reduce maintenance frequency, improve operational safety, and extend the service life of undercarriage components.
